These are the Tamiya Super Grip Radial Tires for the Tamiya M-chassis cars, such as the Mini Cooper. FEATURES: -Super soft, super high traction rubber. -tread pattern is directional (lettering goes on the outside of car). -tread pattern looks similar to tread patter on real high performance radials. INCLUDES: two tires (ie. one pair). does NOT come with foam inserts. SPECS: inside diameter: 1.5" width: 1.0" REQUIRES: Wheels. You don"t NEED foam inserts, but with tires this soft, probably should get some.
